You chose: Arabella should stay single
In the novel, Arabella gets married after her "cure," so this choice diverts from the novel. However, it aligns with certain elements of Arabella's personality and beliefs that are set up throughout the novel. Wyett states that Arabella's delusions helps her believe that "she has material power in her culture through heterosexual relationships" and "that by adhering to the conventions of romance she can delay marriage and thus absorption into the patriarchal order" (Wyett 9). This belief and stance seems to evaporate in the novel when Arabella is cured by her belief in the romances, but perhaps her feelings about men and marriage could have lingered in some other version of the novel. In the 18th century, a woman who chose to remain single (or one who ended up single and missed her chance to marry) would be termed a spinster, a negative term implying that there is something wrong with the woman for being alone. Remaining single for Arabella could potentially be easier given her position in society, but inheritance for an unmarried woman at the time could be questionable.
